Communication and Perception

The scapopod captacula may have tactile receptors, but this is unknown. Scaphopods have lost eyes, tentacles and osphridia found in other molluscs. The buccal cavity has a sub-radular (below the radula) organ which may be chemoreceptive. (Brusca and Brusca, 2003; Jones and Baxter, 1987)
